A combined subframe and fuel tank for use in automobiles, includes a subframe having a seat disposed therein for tightly receiving an extension extending from a fuel tank, whereby the combined subframe and fuel tank form a composite product so as to occupy a small space in the automobile body.

What is claimed is: 
     
       1. A combined subframe and fuel tank for use in automobiles, comprising: a subframe including a seat portion formed therein and a subframe flange disposed around a substantial outer perimeter of said subframe such that said seat portion is independently provided with respect to the subframe flange;   a fuel tank including an extension portion, the extension portion of said fuel tank being supported by the seat of said subframe, said fuel tank further including a fuel tank flange formed around a substantial outer perimeter thereof such that said extension portion is independently provided with respect to the fuel tank flange; and   means for joining said subframe flange to the fuel tank flange so as to tightly support the extension portion of the fuel tank on said seat of the subframe.   
     
     
       2. The combined frame and fuel tank of claim 1, wherein said means for joining is by bolting. 
     
     
       3. The combined frame and fuel tank of claim 2, wherein said means for joining is by welding.
